[0030] Below, this application is described in detail.

[0031] Existing PCB-level power supply systems typically use dedicated power planes. However, when the PCB is large and the power consumption of components is unevenly distributed, it is necessary to design separate power supplies for local areas with high power demands. This is usually achieved by increasing the number or thickness of internal wiring layers. This results in an increase in the number of layers and thickness of the PCB, making the manufacturing of the PCB more difficult and costly.

[0032] The inventors of this application have discovered that by installing a conductive mounting base on a circuit board and connecting a conductive member to the conductive mounting base through a plug-in connection, the conductive member and the circuit board are electrically connected. Current on the circuit board can be conducted through the conductive mounting base and the conductive member to other locations on the circuit board or to other components. This helps reduce the number of circuits on the circuit board, simplifies circuit board design and processing difficulty, and thus reduces the manufacturing cost of the circuit board. Furthermore, the plug-in connection method eliminates soldering, making the processing process simpler, effectively reducing processing difficulty and saving processing costs, thereby achieving excellent processing cost-effectiveness.

[0033] Based on this design concept, the inventor of this application designed a circuit board assembly, which includes a circuit board, at least two conductive mounting seats and at least one conductive member. The conductive mounting seats are connected to the circuit board, and each conductive mounting seat forms a first conductive plug-in structure; the conductive member includes a conductive main body and at least two second conductive plug-in structures connected to the conductive main body, and each first conductive plug-in structure is plugged into at least one second conductive plug-in structure.

[0034] This design installs a conductive mounting seat on the circuit board, the conductive mounting seat is electrically connected to the circuit board, and the second conductive plug-in structure of the conductive member is plugged into the first conductive plug-in structure of the conductive mounting seat, so that the conductive member is electrically connected to the conductive mounting seat. Therefore, the current of the circuit board can be conducted to other positions of the circuit board or to other components through the conductive mounting seat and the conductive main body, which is conducive to reducing the circuit in the circuit board and simplifying the design and processing difficulty of the circuit board. In addition, the plug-in method can eliminate welding, making the processing technology simpler, thereby effectively reducing the processing difficulty, saving processing costs, and having good processing cost-effectiveness. In addition, eliminating the welding process can reduce the risk of damage to the components of the circuit board due to high-temperature welding. In addition, due to the provision of the conductive mounting seat, the conductive member is indirectly connected to the circuit board, reducing the probability of wear and tear on the circuit board caused by the insertion of the conductive member, which is conducive to extending the service life of the circuit board.

[0035] The technical solutions described in the embodiments of this application are applicable to any electronic device that requires a circuit board, such as smartphones, tablet computers, smart hands, televisions, speakers, game consoles, robot driver boards, motor control boards, etc.

[0036] Below, refer to Figures 1 to 12 Some embodiments of the present application are described in detail.

[0038] A first aspect of the present application provides a circuit board assembly, such as Figures 1 to 3 As shown, the circuit board assembly includes a circuit board 1, at least two conductive mounting seats 2 and at least one conductive member 3. The conductive mounting seat 2 is connected to the circuit board 1, and the conductive mounting seat 2 forms a first conductive plug-in structure 21; the conductive member 3 includes a conductive main body 31 and at least two second conductive plug-in structures 32 connected to the conductive main body 31, and each first conductive plug-in structure 21 is plugged into at least one second conductive plug-in structure 32.

[0039] Exemplarily, the second conductive plug-in structure 32 of the conductive member 3 is plugged into the conductive mounting seat 2 along the thickness direction of the circuit board 1, and the conductive main body 31 is located on one side of the circuit board 1 along its thickness direction, and the component 6 is installed on the side of the circuit board 1 facing the conductive main body 31.

[0040] A printed circuit board (PCB) is a type of printed circuit board (PCB). Its core function is to connect components and transmit signals through the combination of an insulating substrate and conductive traces. The PCB consists of a substrate layer, a conductive layer, and a protective layer.

[0041] The conductive mounting base 2 is a mechanical component connected to the circuit board 1 and electrically connected to the conductive layer of the circuit board 1. The conductive mounting base 2 can be connected to the circuit board 1 by plugging, welding, bolting, etc. The conductive mounting base 2 has a first conductive plug structure 21, which plugs into the second conductive plug structure 32 of the conductive member 3, thereby interfitting the conductive mounting base 2 and the conductive member 3, fixing the position of the conductive member 3, and establishing an electrical connection between the conductive member 3 and the circuit board 1. The conductive mounting base 2 can be made of, but is not limited to, copper, copper alloys, aluminum alloys, copper-steel composite structures, etc.

[0042] The conductive member 3 is a mechanical component with conductive properties. The conductive member 3 can be plugged into the first conductive plug structure 21 of the conductive mounting seat 2 through the second conductive plug structure 32, so that the conductive member 3 is installed on the circuit board 1 through the conductive mounting seat 2, and the conductive member 3 is electrically connected to the conductive mounting seat 2, thereby making the conductive member 3 electrically connected to the circuit board 1, and the current of the circuit board 1 can be conducted to other positions of the circuit board 1 or to other components through the conductive mounting seat 2 and the conductive member 3. Exemplarily, the conductive body 31 of the conductive member 3 is an elongated structure, which can be a flat elongated structure or an elongated structure with a circular cross-section. The material of the conductive member 3 can be, but is not limited to, copper, copper alloy, aluminum alloy, copper-steel composite structure, etc.

[0043] It can be understood that the conductive part 3 is plugged into the conductive mounting seat 2 installed on the circuit board 1 by plugging. Therefore, after the operation of welding components 6 on the circuit board 1 is completed, the conductive part 3 can be plugged into the conductive mounting seat 2 to realize the installation of the conductive part 3 on the circuit board 1.

[0044] It should be noted that, in the case of one or more conductive parts 3, all the second conductive plug-in structures 32 of the same conductive part 3 can be plugged into the conductive mounting seat 2 connected to the circuit board 1; in the case of multiple conductive parts 3, some of the second conductive plug-in structures 32 of the same conductive part 3 can be plugged into the conductive mounting seat 2 connected to the circuit board 1, and the remaining second conductive plug-in structures 32 are connected to other conductive parts 3; multiple second conductive plug-in structures 32 of some conductive parts 3 can be respectively connected to other different conductive parts 3.

[0045] The circuit board 1 is provided with the conductive mounting seat 2, the conductive mounting seat 2 is electrically connected with the circuit board 1, the second conductive plug-in structure 32 of the conductive part 3 is plugged with the first conductive plug-in structure 21 of the conductive mounting seat 2, so that the conductive part 3 is electrically connected with the conductive mounting seat 2, therefore, the current of the circuit board 1 can be conducted to other positions of the circuit board 1 or other components through the conductive mounting seat 2 and the conductive main body 31, which is beneficial to reduce the circuit of the circuit board 1 and simplify the design and processing difficulty of the circuit board 1. Moreover, the plug-in mode can save the welding, so that the processing technology is simpler, thereby effectively reducing the processing difficulty and saving the processing cost, and having good processing cost benefit. In addition, the welding process is saved, which can reduce the risk of damage to the components 6 of the circuit board 1 caused by high-temperature welding of the conductive part 3. Moreover, due to the arrangement of the conductive mounting seat 2, the conductive part 3 is indirectly connected with the circuit board 1, which reduces the probability of wear of the circuit board 1 caused by the plug-in of the conductive part 3, and is beneficial to prolong the service life of the circuit board 1.

[0046] It should be noted that the conductive mounting seat 2 can be connected with the circuit board 1 after the components 6 are welded on the circuit board 1, for example, in the case that the conductive mounting seat 2 is connected with the circuit board 1 by a non-heating mode (for example, a plug-in mode), the conductive mounting seat 2 can be connected with the circuit board 1 after the components 6 are welded. The conductive mounting seat 2 can also be connected with the circuit board 1 before the components 6 are welded on the circuit board 1, for example, in the case that the conductive mounting seat 2 is connected with the circuit board 1 by welding, the conductive mounting seat 2 is welded on the circuit board 1 before the components 6 are welded, which can reduce the damage to the components 6 caused by welding of the conductive mounting seat 2.

[0047] In some embodiments of the present application, as shown in Figure 3 and Figure 4 of the drawings, one of the first conductive plug-in structure 21 and the second conductive plug-in structure 32 is a plug-in slot 21a, and the other is a plug-in protrusion 32a which is plugged with the plug-in slot 21a.

[0048] For example, as shown in Figure 3 and Figure 4 of the drawings, the first conductive plug-in structure 21 is a plug-in slot 21a, and the second conductive plug-in structure 32 is a plug-in protrusion 32a which is plugged with the plug-in slot 21a.

[0049] For example, the second conductive plug-in structure 32 is a plug-in slot 21a, and the first conductive plug-in structure 21 is a plug-in protrusion 32a which is plugged with the plug-in slot 21a.

[0050] In this way, the mutual plug-in connection of the first conductive plug-in structure 21 and the second conductive plug-in structure 32 is realized, the connection operation of the conductive part 3 and the conductive mounting seat 2 is simplified, the connection difficulty is simplified, and the manufacturing cost is reduced.

[0051] Exemplarily, the cross-section of the outer contour of the plug-in protrusion 32a may be, but is not limited to, a circle, an ellipse, a polygon, or other regular or irregular shapes. Correspondingly, the cross-section of the plug-in slot 21a may be, but is not limited to, a circle, an ellipse, a polygon, or other regular or irregular shapes. The cross-section is a cross-section perpendicular to the thickness direction of the circuit board 1. It is understandable that the cross-sections of the outer contour of the plug-in protrusion 32a may be the same or different at various locations. The cross-sections of the plug-in slot 21a may be the same or different at various locations. As long as the plug-in protrusion 32a and the plug-in slot 21a are compatible, their relative positions can be defined after insertion, and their specific shapes are not limited here.

[0052] In some embodiments of the present application, the insertion protrusion 32a is interference fit with the insertion groove 21a.

[0053] It is understood that the fit between the insertion protrusion 32a and the insertion groove 21a is not limited to an interference fit. Optionally, the insertion protrusion 32a and the insertion groove 21a can be clearance fit or transition fit, with the clearance controlled within a relatively small range to fix the relative position of the two, and no further restrictions are made here.

[0054] In some embodiments of the present application, Figure 4 As shown, the surface of the inserting protrusion 32 a that contacts the inserting groove 21 a and / or the surface of the inserting groove 21 a that contacts the inserting protrusion 32 a is provided with a first conductive plating layer 51 .

[0055] Exemplarily, at least a portion of the surface where the inserting protrusion 32 a contacts the inserting groove 21 a is provided with a first conductive plating layer 51 .

[0056] Exemplarily, at least a portion of the entire surface of the inserting protrusion 32 a in the area contacting the inserting groove 21 a is provided with the first conductive plating layer 51 .

[0057] Exemplarily, at least a portion of the entire slot wall of the plugging slot 21 a in the region contacting the plugging protrusion 32 a is provided with the first conductive plating layer 51 .

[0058] Exemplarily, the first conductive plating layer 51 includes at least one of a gold plating layer, a silver plating layer, and a nickel plating layer.

[0059] By performing a plating process on the contact portion between the plug-in protrusion 32a and the plug-in slot 21a, the contact impedance can be reduced, thereby improving the electrical conductivity and the electrical reliability of the circuit board assembly.

[0060] It can be understood that the present application is not limited to the case where both the plug-in protrusion 32a and the plug-in slot 21a are provided with the first conductive plating 51. It is also possible that neither the plug-in protrusion 32a nor the plug-in slot 21a is provided with the first conductive plating 51, or that one of them is provided with the first conductive plating 51 and the other is not provided with the first conductive plating 51.

[0061] In some embodiments of the present application, Figure 5 and Figure 6 As shown, the first conductive plug-in structure 21 is a plug-in slot 21a, the second conductive plug-in structure 32 is a plug-in protrusion 32a plugged into the plug-in slot 21a, each conductive mounting seat 2 is formed with a protrusion 22 on the side opposite to the plug-in slot 21a, and the circuit board 1 is formed with a mounting hole 11, and the protrusion 22 is plugged into the mounting hole 11.

[0062] Exemplarily, a portion of each conductive mounting seat 2 is deformed to bulge toward the side where the circuit board 1 is provided, forming a protrusion 22 on the side facing the circuit board 1 and forming an insertion slot 21 a on the side away from the circuit board 1 .

[0063] Exemplarily, the cross-section of the outer contour of the protrusion 22 may be, but is not limited to, a circle, an ellipse, a polygon, or other regular or irregular shapes. Correspondingly, the cross-section of the mounting hole 11 may be, but is not limited to, a circle, an ellipse, a polygon, or other regular or irregular shapes. The cross-section is a cross-section perpendicular to the thickness direction of the circuit board 1. It is understandable that the cross-sections of the outer contour of the protrusion 22 may be the same or different at various locations. The cross-sections of the mounting hole 11 may be the same or different at various locations. As long as the protrusion 22 is compatible with the mounting hole 11, the relative position of the two can be defined after insertion, and the specific shapes of the two are not limited here.

[0064] In this way, the protrusion 22 is formed on the back side of the insertion slot 21a, which not only allows the conductive mounting seat 2 to be connected to the circuit board 1 by plugging the protrusion 22 into the mounting hole 11, but also helps to reduce the volume of the conductive mounting seat 2 and save space. The conductive mounting seat 2 is connected to the circuit board 1 by plugging, so that the contact area between the conductive mounting seat 2 and the circuit board 1 is relatively large, improving the reliability of the mechanical connection and the electrical connection. In addition, the conductive mounting seat 2 is connected to the circuit board 1 by plugging, and the conductive mounting seat 2 can be installed after the components 6 are soldered, and then the conductive part 3 can be inserted. In this way, the installation operation is further simplified and damage to the components 6 is further reduced.

[0065] It is understandable that the connection method between the conductive mounting base 2 and the circuit board 1 is not limited to plug-in connection, and can also be bolt connection, welding, etc., which is not specifically limited here.

[0066] In some embodiments of the present application, Figure 5 and Figure 6 As shown, the conductive mounting seat 2 further includes an abutting portion 23 surrounding the protruding portion 22 , and the abutting portion 23 abuts against a surface of the circuit board 1 facing the conductive main body portion 31 .

[0067] It should be noted that part of the conductive mounting seat 2 is deformed to bulge toward the side where the circuit board 1 is provided, forming a protrusion 22 on the side facing the circuit board 1 and a plug-in slot 21a on the side away from the circuit board 1, and the remaining part of the conductive mounting seat 2 forms an abutment portion 23 surrounding the protrusion 22.

[0068] Exemplarily, the conductive mounting base 2 is made of a plate through a stamping process.

[0069] The arrangement of the abutting portion 23 increases the contact area between the conductive mounting base 2 and the circuit board 1 , thereby improving the connection reliability between the conductive mounting base 2 and the circuit board 1 .

[0070] In some embodiments of the present application, Figure 7 As shown, the circuit board assembly further includes a spacer 4 , which is detachably sleeved on the outer periphery of the plug-in protrusion 32 a and abuts between the abutting portion 23 and the conductive main body 31 .

[0071] In this way, by arranging the pad 4 between the abutment portion 23 and the conductive main body portion 31, the distance between the conductive main body portion 31 and the circuit board 1 can be changed, so that components 6 of different sizes can be arranged on the side of the circuit board 1 facing the conductive main body portion 31, thereby improving the applicability of the conductive part 3.

[0072] Exemplarily, there are more than two pads 4, and all pads 4 have at least two pads 4 with different thicknesses. By selecting at least one of all pads 4 to be placed outside the plug-in protrusion 32a, the conductive main body 31 can be adjusted to multiple positions with different spacings from the circuit board 1 to suit different usage scenarios.

[0073] In some embodiments of the present application, the protrusion 22 is interference fit with the mounting hole 11 .

[0074] It is understood that the fit between the protrusion 22 and the mounting hole 11 is not limited to an interference fit. Optionally, the insertion protrusion 32a and the insertion groove 21a have a clearance fit or a transition fit, with the clearance controlled within a relatively small range to fix the relative position of the two, and no further restrictions are made here.

[0075] In some embodiments of the present application, Figure 6 As shown, the surface of the protrusion 22 in contact with the mounting hole 11 and / or the surface of the mounting hole 11 in contact with the protrusion 22 is provided with a second conductive plating layer 52 .

[0076] Exemplarily, at least a portion of the surface where the protrusion 22 contacts the mounting hole 11 is provided with a second conductive plating layer 52 .

[0077] Exemplarily, at least a portion of the entire surface of the protrusion 22 in the area contacting the mounting hole 11 is provided with the second conductive plating layer 52 .

[0078] Exemplarily, at least a portion of the area in contact with the protrusion 22 in the entire hole wall of the mounting hole 11 is provided with the second conductive plating layer 52 .

[0079] Exemplarily, the second conductive plating layer 52 includes at least one of a gold plating layer, a silver plating layer, and a nickel plating layer.

[0080] By performing a plating process on the contact portion between the protrusion 22 and the mounting hole 11 , the contact impedance can be reduced, thereby improving the electrical conductivity and the electrical reliability of the circuit board assembly.

[0081] In some embodiments of the present application, the conductive body portion 31 and the plug-in protrusion 32 a are formed as an integrally formed structure.

[0082] In this way, the connection reliability between the conductive body portion 31 and the insertion protrusion 32a is improved, the conductive resistance is reduced, and the conductivity is improved. In addition, the manufacturing efficiency of the conductive member 3 is high.

[0083] It is understandable that the conductive body portion 31 and the plug protrusion 32a are not limited to being an integrally formed structure, and the conductive body portion 31 and the plug protrusion 32a may also be connected by welding, etc. This is not specifically limited here.

[0084] In some embodiments of the present application, in any direction perpendicular to the thickness direction of the circuit board 1 , the difference between the size of the protrusion 22 and the size of the mounting hole 11 is greater than or equal to 0.2 mm and less than or equal to 0.5 mm.

[0085] Exemplarily, the cross-sections of the outer circumference of the protrusion 22 and the hole wall of the mounting hole 11 are both circular, and the difference between the diameter of the outer circumference of the protrusion 22 and the diameter of the hole wall of the mounting hole 11 is greater than or equal to 0.2 mm and less than or equal to 0.5 mm.

[0086] Illustratively, in any direction perpendicular to the thickness direction of the circuit board 1, the difference between the size of the protrusion 22 and the size of the mounting hole 11 may be, but is not limited to, 0.2 mm, 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm, 0.25 mm, 0.26 mm, 0.27 mm, 0.28 mm, 0.29 mm, 0.3 mm, 0.31 mm, 0.32 mm, 0.33 mm, 0.34 mm, 0.35 mm, 0.36 mm, 0.37 mm, 0.38 mm, 0.39 mm, 0.4 mm, 0.41 mm, 0.42 mm, 0.43 mm, 0.44 mm, 0.45 mm, 0.46 mm, 0.47 mm, 0.48 mm, 0.49 mm, or 0.5 mm.

[0087] In this way, the protrusion 22 and the mounting hole 11 are interference fit, and the two can be securely plugged together. Moreover, it is not easy to insert the protrusion 22 into the mounting hole 11 due to a large difference, thereby improving the smoothness of the plugging operation.

[0088] In some embodiments of the present application, Figure 2 and Figure 3 As shown, the conductive body portion 31 is a flat structure, and the thickness direction of the conductive body portion 31 is consistent with the thickness direction of the circuit board 1 .

[0089] It is understood that a flat structure refers to a structure whose thickness is much smaller than its length and width, including plate-like or sheet-like structures. The conductive body portion 31 is a flat structure, and the thickness direction of the conductive body portion 31 is consistent with the thickness direction of the circuit board 1, that is, the conductive body portion 31 is parallel to the circuit board 1.

[0090] For example, Figure 2 and Figure 3 As shown, the conductive body 31 is a flat, long strip structure, with a plug-in protrusion 32a at each end along its length. The plug-in protrusions 32a are located on the same side of the conductive body 31 along its thickness direction.

[0091] In this way, by arranging the conductive body portion 31 to be parallel to the circuit board 1 , the influence of the conductive body portion 31 on the heat dissipation air duct is reduced, thereby improving the heat dissipation effect.

[0092] In some embodiments of the present application, Figures 8 to 10 As shown, there are more than two conductive parts 3, and the conductive main body 31 of at least one conductive part 3 is formed with multiple spaced third conductive plug-in structures 311, and each third conductive plug-in structure 311 of the conductive part 3 can be plugged with any second conductive plug-in structure 32 of another conductive part 3.

[0093] Exemplarily, the conductive main body portion 31 is a flat, long strip structure, and the long strip structure is provided with a plurality of third conductive plug-in structures 311 arranged at intervals along its length direction.

[0094] Exemplarily, the second conductive plug-in structure 32 is a plug-in protrusion 32 a , and the third conductive plug-in structure 311 is a plug-in hole 311 a . The plug-in protrusion 32 a can be plugged into the plug-in hole 311 a .

[0095] Exemplarily, the second conductive plug-in structure 32 is a plug-in slot 21 a , and the third conductive plug-in structure 311 is a protruding structure, which can be plugged into the plug-in slot 21 a .

[0096] In this way, multiple conductive members 3 can be connected to facilitate the use of multiple conductive members 3 for the power supply topology of the circuit board 1, and a variety of different conductive structures can be flexibly formed.

[0097] It is understandable that the number of the conductive members 3 is not limited to more than two, and may also be one.

[0098] In the embodiments of the present application, a plurality means two or more.

[0099] In some embodiments of the present application, Figure 8 As shown, the third conductive plug-in structure 311 is a plug-in hole 311 a , and the second conductive plug-in structure 32 is a plug-in protrusion 32 a plugged and matched with the third conductive plug-in structure 311 .

[0100] In this way, the structure of the conductive member 3 is simple, the manufacturing cost is low, and the connection operation between the conductive members 3 is convenient and the connection reliability is high.

[0101] Exemplarily, the sizes of the conductive members 3 are set to be the same, that is, the shapes and sizes of the conductive members 3 in all directions are the same.

[0102] Exemplarily, at least two conductive members 3 have different sizes, that is, the conductive members 3 have different shapes or sizes in at least one direction.

[0103] Exemplarily, the spacings between adjacent plug holes 311 a are set to be the same.

[0104] Exemplarily, the intervals between adjacent plug holes 311 a are set to be different.

[0105] For example, Figure 9As shown, there are four or more conductive members 3, each with a plugging protrusion 32a at both ends. The conductive body 31 of the conductive member 3 is formed with multiple plugging holes 311a. The two plugging protrusions 32a of the first conductive member 3 are respectively plugged into two conductive mounting seats 2 on the circuit board 1, one plugging protrusion 32a of the second conductive member 3 is plugged into one plugging hole 311a of the first conductive member 3, one plugging protrusion 32a of the third conductive member 3 is plugged into one plugging hole 311a of the second conductive member 3, and one plugging protrusion 32a of the fourth conductive member 3 is plugged into another plugging hole 311a of the second conductive member 3. The other plugging protrusions 32a of the second conductive member 3, the third conductive member 3, and the fourth conductive member 3 can be plugged into the conductive mounting seat 2 on the circuit board 1 or into the plugging hole 311a of another conductive member 3. In this way, a variety of different conductive structures can be formed. The specific structure formed can be determined according to the connection requirements and is not specifically limited here.

[0106] For example, Figure 10 As shown, there are more than three conductive members 3, and each conductive member 3 has a plugging protrusion 32a at both ends. The conductive main body 31 of at least one conductive member 3 is formed with multiple plugging holes 311a. The first conductive member 3 has multiple plugging holes 311a. The two plugging protrusions 32a of the first conductive member 3 are respectively plugged into the two conductive mounting seats 2 on the circuit board 1. One plugging protrusion 32a of the second conductive member 3 is plugged into one plugging hole 311a of the first conductive member 3. One plugging protrusion 32a of the third conductive member 3 is plugged into another plugging hole 311a of the first conductive member 3. Another plugging protrusion 32a of the second conductive member 3 and another plugging protrusion 32a of the third conductive member 3 can be plugged into the conductive mounting seat 2 on the circuit board 1 or into the plugging hole 311a of another conductive member 3. In this way, a variety of different conductive structures can be formed. The specific structure formed can be determined according to the connection requirements and is not specifically limited here.

[0107] In some embodiments of the present application, the conductive member 3 includes two second conductive plug-in structures 32 , and at least part of the third conductive plug-in structure 311 is arranged between the two second conductive plug-in structures 32 .

[0108] Exemplarily, the two second conductive plug structures 32 are respectively disposed at opposite ends of the conductive body portion 31 along its length direction, and all the third conductive plug structures 311 are arranged between the two second conductive plug structures 32 along the length direction of the conductive body portion 31 .

[0109] In this way, the connection between the conductive members 3 can be carried out in a larger range, thereby achieving current conduction over a longer distance.

[0110] In some embodiments of the present application, Figure 11 and Figure 12 As shown, the conductive main body portion 31 includes a first portion 312 and a second portion 313. The first portion 312 has a sliding cavity 3121 extending along a first direction. One end of the first portion 312 along the first direction is provided with a second conductive plug-in structure 32. The other end of the sliding cavity 3121 along the first direction is formed with an opening. One end of the second portion 313 can be movably extended into the sliding cavity 3121 along the first direction through the opening. The other end of the second portion 313 is provided with a second conductive plug-in structure 32.

[0111] For example, the first portion 312 and the plug-in protrusion 32a connected thereto are formed into an integrally formed structure. Alternatively, the first portion 312 and the plug-in protrusion 32a connected thereto are connected by welding.

[0112] For example, the second portion 313 and the plug-in protrusion 32a connected thereto are formed into an integral structure. Alternatively, the second portion 313 and the plug-in protrusion 32a connected thereto are connected by welding.

[0113] In this way, by extending the second part 313 into or pulling it out of the sliding cavity 3121 along the first direction, the size of the conductive main body part 31 along the first direction can be adjusted, thereby adjusting the spacing between the second conductive plug-in structures 32 located at the opposite ends of the conductive main body part 31, adjusting the distance of current transmission, and expanding the applicable scenarios of the conductive part 3.

[0114] It is understandable that the conductive body portion 31 is not limited to a structure with adjustable length, but may also be a structure with fixed size.

[0115] In some embodiments of the present application, Figure 11 As shown, the cavity wall of the sliding cavity 3121 is provided with an elastic locking member 3124 , and the second portion 313 is provided with a plurality of locking grooves 3132 spaced apart along the first direction, and the elastic locking member 3124 is engaged with one of the locking grooves 3132 .

[0116] Exemplarily, the elastic retaining member 3124 is a metal spring.

[0117] After the first part 312 moves to an appropriate position along the first direction, the relative positions of the first part 312 and the second part 313 are fixed by the engagement of the elastic locking member 3124 with the locking groove 3132, and the length of the conductive main body 31 is locked, thereby adjusting the distance of current transmission to expand the applicable scenarios of the conductive member 3.

[0118] In some embodiments of the present application, Figure 13As shown, one of the cavity wall of the sliding cavity 3121 and the outer peripheral surface of the second portion 313 is provided with an elastic protrusion 3122 , and the other elastically abuts against the elastic protrusion 3122 .

[0119] Exemplarily, the elastic protrusion 3122 is a metal spring.

[0120] Exemplarily, a third conductive coating 53 is provided at a portion of the sliding cavity 3121 and the second portion 313 where the elastic protrusion 3122 contacts.

[0121] By providing the elastic protrusion 3122 , the cavity wall of the sliding cavity 3121 and the outer peripheral surface of the second portion 313 are closely fitted together, so that the two have good contact, reducing contact impedance and improving conductivity.

[0122] In some embodiments of the present application, Figure 13 As shown, one of the cavity wall of the sliding cavity 3121 and the outer peripheral surface of the second portion 313 is provided with a sliding groove 3123 extending along the first direction, and the other is provided with a sliding protrusion 3131 extending along the first direction, and the sliding protrusion 3131 is slidably fitted in the sliding groove 3123.

[0123] Exemplarily, there are one, two, three or more sliding protrusions 3131 , and correspondingly, there are one, two, three or more sliding grooves 3123 .

[0124] Exemplarily, the surface of the sliding protrusion 3131 and the wall of the sliding groove 3123 are both provided with a third conductive coating 53 .

[0125] In this way, the cooperation between the sliding protrusion 3131 and the sliding groove 3123 achieves a sliding connection between the first portion 312 and the second portion 313 along the first direction, improving the stability of the connection between the two. In addition, the cooperation between the sliding protrusion 3131 and the sliding groove 3123 also increases the contact area between the first portion 312 and the second portion 313, reducing contact impedance and lowering the impedance of the entire conductive member 3.

[0126] In some embodiments of the present application, Figure 13 As shown, at least a portion of the cavity wall of the sliding cavity 3121 contacts at least a portion of the outer peripheral surface of the second portion 313 , and at least one of the contacting surfaces is provided with a third conductive plating layer 53 .

[0127] Exemplarily, the third conductive plating layer 53 includes at least one of a gold plating layer, a silver plating layer, and a nickel plating layer.

[0128] By performing a plating treatment on the contact portion between the cavity wall of the sliding cavity 3121 and the outer peripheral surface of the second portion 313, the contact impedance can be reduced, thereby improving the electrical conductivity and the electrical reliability of the circuit board assembly.

[0129] Of course, it is understood that the arrangement of the cavity wall of the sliding cavity 3121 and the outer peripheral surface of the second portion 313 is not limited thereto. The contact surface between the cavity wall of the sliding cavity 3121 and the second portion 313 may also not be provided with the third conductive coating 53 .

[0130] In some embodiments of the present application, Figure 13 As shown, one of the two cavity walls of the sliding cavity 3121 that are opposite to each other along the thickness direction of the first part 312 is formed with an elastic protrusion 3122, and the other is formed with a sliding protrusion 3131. The elastic protrusion 3122 elastically abuts against one surface of the second part 313, and the sliding protrusion 3131 slides in cooperation with a sliding groove 3123 provided on the other surface of the second part 313.

[0131] In this way, opposite sides of the second portion 313 along its thickness direction are in contact with the sliding cavity 3121, thereby improving the stability of the sliding connection between the first portion 312 and the second portion 313, increasing the contact area, improving the reliability of the electrical connection, and improving the electrical conductivity.

[0132] The second aspect of the present application provides a circuit board conductive accessory, such as Figures 1 to 3 As shown, the conductive accessories of the circuit board include at least two conductive mounting seats 2 and at least one conductive member 3. The conductive mounting seats 2 are used to connect to the circuit board 1. Each conductive mounting seat 2 forms a first conductive plug-in structure 21. The conductive member 3 includes a conductive main body 31 and at least two second conductive plug-in structures 32 connected to the conductive main body 31. Each first conductive plug-in structure 21 is plugged into at least one second conductive plug-in structure 32.

[0133] The second conductive plug-in structure 32 of the conductive member 3 is plugged into the first conductive plug-in structure 21 of the conductive mounting seat 2, so that the conductive member 3 is electrically connected to the conductive mounting seat 2. Therefore, the current of the circuit board 1 can be conducted to other positions of the circuit board 1 or to other components through the conductive mounting seat 2 and the conductive main body 31, which is beneficial to reducing the circuit in the circuit board 1 and simplifying the design and processing difficulty of the circuit board 1. In addition, the plug-in method can eliminate welding, making the processing technology simpler, thereby effectively reducing the processing difficulty, saving processing costs, and having good processing cost-effectiveness. In addition, eliminating the welding process can reduce the risk of damage to the components 6 of the circuit board 1 due to high-temperature welding. In addition, due to the provision of the conductive mounting seat 2, the conductive member 3 is indirectly connected to the circuit board 1. Compared with the method of directly plugging the conductive member 3 into the circuit board 1, the indirect connection reduces the probability of the conductive member 3 causing wear to the circuit board 1, which is beneficial to extending the service life of the circuit board 1.

[0134] In some embodiments of the present application, Figures 4 to 6As shown, the circuit board 1 is formed with a mounting hole 11, the first conductive plug-in structure is a plug-in slot 21a, the second conductive plug-in structure 32 is a plug-in protrusion 32a plugged into the plug-in slot 21a, and each conductive mounting seat 2 is formed with a protrusion 22 on the side opposite to the plug-in slot 21a, and the protrusion 22 is plugged into the mounting hole 11.

[0135] Exemplarily, a portion of each conductive mounting seat 2 is deformed to bulge toward the side where the circuit board 1 is provided, forming a protrusion 22 on the side facing the circuit board 1 and forming a plug-in slot 21a serving as the first conductive plug-in structure 21 on the side away from the circuit board 1.

[0136] In this way, the conductive part 3 can be plugged into the plug-in groove 21a of the conductive mounting seat 2 through its plug-in protrusion 32a, thereby realizing the connection between the conductive part 3 and the conductive mounting seat 2, thereby realizing the indirect connection between the conductive part 3 and the circuit board 1. The current of the circuit board 1 can be conducted to other positions of the circuit board 1 or to other components through the conductive part 3, which is beneficial to reducing the circuit in the circuit board 1 and simplifying the design and processing difficulty of the circuit board 1.

[0137] In some embodiments of the present application, Figures 8 to 10 As shown, there are more than two conductive members 3 , and the conductive body 31 of at least one conductive member 3 is formed with a plurality of spaced-apart plug holes 311 a , and each plug hole 311 a of the conductive member 3 can be plugged with any plug protrusion 32 a of another conductive member 3 .

[0138] In this way, multiple conductive members 3 can be connected to facilitate the use of multiple conductive members 3 to implement the power supply topology of the circuit board 1, and a variety of different conductive structures can be flexibly formed. In addition, the conductive members 3 have a simple structure and low manufacturing cost, and the connection operation between the conductive members 3 is convenient and the connection reliability is high.

[0139] In some embodiments of the present application, the conductive main body 31 includes a first part 312 and a second part 313, the first part 312 has a sliding cavity 3121 extending along the first direction, one end of the first part 312 along the first direction is provided with a second conductive plug-in structure 32, the other end of the sliding cavity 3121 along the first direction is formed with an opening, one end of the second part 313 can be movably extended into the sliding cavity 3121 along the first direction through the opening, the other end of the second part 313 is provided with a second conductive plug-in structure 32, the cavity wall of the sliding cavity 3121 is provided with an elastic locking member 3124, the second part 313 is provided with a plurality of locking grooves 3132 spaced apart along the first direction, and the elastic locking member 3124 is locked with one of the locking grooves 3132.

[0140] In some embodiments of the present application, the conductive member 3 is made of copper, and the cross-sectional area of ​​the conductive body portion 31 of the conductive member 3 is greater than or equal to 0.1 mm. 2 and less than or equal to 100 mm2 .

[0141] It can be understood that the cross section of the conductive body portion 31 is a cross section perpendicular to the length direction of the conductive body portion 31 .

[0142] For example, the cross-sectional area of ​​the conductive body portion 31 of the conductive member 3 may be, but is not limited to, 0.1 mm 2 , 1mm 2 , 2mm 2 , 3mm 2 , 4mm 2 , 5mm 2 , 6mm 2 , 7mm 2 , 8mm 2 , 9mm 2 , 10mm 2 , 20mm 2 , 30mm 2 , 40mm 2 , 50mm 2 , 60mm 2 , 70mm 2 , 80mm 2 , 90mm 2 , 100mm 2 .

[0143] In some embodiments of the present application, the conductive member 3 is made of copper, and the cross-sectional area of ​​the conductive body portion 31 of the conductive member 3 is greater than or equal to 10 mm. 2 and less than or equal to 100 mm 2 .

[0144] Thus, the cross-sectional area of ​​the conductive body 31 is large enough to have a high current carrying capacity, which can meet high current requirements and reduce energy loss. In addition, the cross-sectional area of ​​the conductive body 31 is not too large to cause problems such as large space occupation and material waste.

[0145] In some embodiments of the present application, the outer surface of the conductive body portion 31 of the conductive member 3 is covered with an insulating layer.

[0146] For example, the insulating layer may be formed by coating an insulating varnish. The insulating layer may be an insulating sleeve sleeved outside the conductive body 31. The insulating layer may be formed by depositing an insulating material such as aluminum oxide or ceramic on a copper surface through an electroplating process.

[0147] In this way, the risk of current leakage or short circuit accidents caused by accidental contact between the conductive part 3 and other conductive components is reduced, external factors such as moisture, dust, and chemical corrosion are resisted, and the service life of the conductive part 3 is extended.

[0148] In some embodiments of the present application, the dimension of the contact portion between the protrusion 22 of the conductive mounting seat 2 and the mounting hole 11 of the circuit board 1 along the thickness direction of the circuit board 1 is greater than or equal to 1.6 mm and less than or equal to 10 mm.

[0149] Exemplarily, the dimensions of the contact area between the protrusion 22 of the conductive mounting seat 2 and the mounting hole 11 of the circuit board 1 along the thickness direction of the circuit board 1 can be but are not limited to 1.6mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, or 10mm.

[0150] As a specific example, the outer peripheral surface of the protrusion 22 of the conductive mounting base 2 is provided with a gold-plated layer, and the friction coefficient between the gold-plated layer and the material FR-4 (Flame-Retardant 4) of the hole wall of the mounting hole 11 of the circuit board 1 is 0.3 μm or more and 0.4 μm or less. Elastic modulus of the base material layer (material FR-4) of the circuit board 1 The cross-section of the outer peripheral surface of the protrusion 22 of the conductive mounting seat 2 and the hole wall of the mounting hole 11 are both circular, and the difference between the diameter of the outer peripheral surface of the protrusion 22 and the diameter of the hole wall of the mounting hole 11 is Greater than or equal to 0.2mm and less than or equal to 0.5mm. The crimping force between the conductive mounting base 2 and the circuit board 1 is F, and the calculation formula of F is: ,in, is the contact area, ,in is the dimension of the contact area between the protrusion 22 of the conductive mounting seat 2 and the mounting hole 11 of the circuit board 1 along the thickness direction of the circuit board 1, is the contact pressure, , it can be deduced from the above three formulas, ,in, Greater than or equal to 0.3μm and less than or equal to 0.4μm; Greater than or equal to 15 GPa and less than or equal to 20 GPa; Greater than or equal to 0.2mm and less than or equal to 0.5mm; Greater than or equal to 1.6mm and less than or equal to 10mm, thus, it can be calculated that =0.3*15*0.2*1.6* 4.5N, the crimping force F directly reflects the firmness of the connection between the conductive mounting base 2 and the circuit board 1. The crimping force between the two is large enough to meet the insertion strength requirements of the conductive mounting base 2 on the circuit board 1.

[0151] A third aspect of the present application provides an electronic device, which includes the circuit board assembly provided by the first aspect.

[0152] Since the circuit board assembly provided in the first aspect has low processing costs and the risk of damage to the components 6 of the circuit board 1 is low, the processing costs of the electronic device including the circuit board assembly are low and the risk of damage to the components 6 of the circuit board 1 is low.
